A study published in npj Parkinsons Disease in 2025 delves into the striatum's functional gradients in Parkinson's patients with cognitive decline.
The research reveals how changes in the striatum accompany continuous cognitive impairment in Parkinson's disease.
The striatum's role in both motor control and cognitive functions makes it a key focus for understanding cognitive decline in Parkinson's.
Advanced neuroimaging techniques were employed to map functional gradients in Parkinson's patients with varying cognitive impairments.
Disrupted striatal gradients correlated with worsening cognitive deficits in Parkinson's, indicating altered connectivity patterns.
The study links gene expression patterns in the striatum to changes in functional gradients, revealing pathways related to Parkinson's pathology.
Notable genes involved in dopamine signaling and mitochondrial function showed differential expression along the altered striatal gradients.
Identifying early biomarkers for cognitive impairment through gradient patterns and gene expression could revolutionize clinical diagnosis and interventions.
This research emphasizes network dynamics over localized damage, offering insights into neurodegenerative cognitive deficits in Parkinson's disease.
The study sets a precedent for holistic brain mapping in neurological diseases by integrating functional MRI and transcriptomic data.
